The TL3844BDR-8 from Texas Instruments is part of the TLx84xB series of current-mode PWM controllers. These integrated circuits are designed to facilitate the implementation of fixed-frequency current-mode control schemes for off-line or DC-to-DC converters with minimal external components.
Key features include a low start-up current of less than 0.5mA and trimmed oscillator discharge current. The device supports current mode operation up to 500kHz, automatic feed-forward compensation, and latching PWM for cycle-by-cycle current limiting. It also incorporates an internally trimmed reference with undervoltage lockout and a high-current totem-pole output stage.
The TL3844BDR-8 operates within a voltage range of 10V to 30V and has a maximum duty cycle of 48%. Its operating temperature range is from 0°C to 70°C. The controller is housed in an 8-SOIC package and is suitable for surface mount applications.
This controller is ideal for various switching regulator applications, including those requiring boost, flyback, or forward topologies. Its design considerations include features like double-pulse suppression and undervoltage lockout with hysteresis.
